Great once installed

Jan 27, 2018

Works as described but installation was a pain. I have a warmoth tele neck that I installed it to. I had to cut back the nut slot a little to fit the new bone nut and fret in place. I thought it would just drop in.. I wasn't anticipating that but my skills didn't let me down. I filed the nut and fret down on both sides a little, added some super glue and now it works great. i have a bigsby so tunning is a breeze now!

A Lot Less Hassle Than Slotting.

Resolves the nut-string height issue with a simple and easy installation. Worked perfect on my Heritage 16.

An Excellent Product!

Apr 30, 2016

I bought two of these, one Gibson-style and one Fender-style for two of my favorite project guitars, an Epiphone LPX and my Jazz-O-Caster parts guitar. The Gibson was a near drop-in, needing only some trimming and shaping for a perfect fit. The Fender was slightly more challenging, as the neck on the Jazz-O-Caster never saw the inside of any Fender-approved factory! It required a 1/32" shim underneath for a proper fit, and some sanding to make room for the tang. There was a marked increase in the brightness of tone for both instruments, as well as improved intonation. This is MUCH easier than installing a traditional nut, and nearly foolproof IF you follow the instructions. Thanks, Stewart-Macdonald, for stocking such a well-engineered product.

Zero Glide Query

Jun 23, 2025
I have a BC-350 banjo with the zero glide nut. It has been problem-free but I'm curious how this is an improvement over the zero nut found on budget European guitars since practically the beginning of time. I repaired instruments for decades and always regarded the zero fret as a marker of an inferior mass-produced instrument. No criticism of the Gold Tone zero glide is in any way implied here but I am confused.

Acoustic Glide Nut

Oct 7, 2016

I installed this on an old Alvarez acoustic that used to belong to my Dad. The strings had started to buzz badly and the bridge height was maxed out so I knew it must be the nut. Took about an hour to cut down the new nut and shape with the Drexel tool; sided/polished the frets and installed glide nut with the tallest feet wire. Worked like a charm and no more buzzing. Even lowed the bridge down to a reasonable height as well. Great product and easy to install.
